Archive for the ‘Critical Thinking’ Category

This article from the Denver Post stresses the usefulness of philosophy, including how “emphasis on informal and symbolic logic” helps with computer science.  In accounts of philosophy curricula, unfortunately, reference to informal logic is typically just name-dropping, as the textbook authors are mostly not scholars in the field, and instructors rarely have any relevant training.  That seems to be the case here:  Colorado State has only one logician on faculty, and he specializes in formal logic.

This problem is deeply ironic, for the scholarship being neglected was developed for the very purpose of filling the gap between logical theory and logical practice. Much scholarship in symbolic logic may be irrelevant to undergraduate pedagogy, but informal logic is a movement developed substantially for the purpose of creating an approach to logic that would be more relevant to students.

When philosophers appeal to “informal logic” or philosophers claim ownership over the teaching of “critical thinking,” it verges on fraud.  The baiting with informal logic scholarship devoted to critical thinking and switching it for a loose distillation of the cultural standards in the discipline of philosophy is going to catch up with us eventually.

It’s time for philosophers to wake up and put our money, our faculty positions, our textbook buying power, and our textbook reviews where the scholarship is.  Philosophy can be highly relevant if we hold ourselves to higher scholarly standards.

As anyone who has attended one of Erik Krabbe‘s talks knows, doodles, sketches, and cartoons are signs of great genius. I first had the pleasure of seeing his drawings in a CRRAR summer seminar a few years ago. I have to admit that being engaged by the various drawings he used there, and in the talks of his that I’ve had the good fortune to attend since then, has inspired me to re-incorporate that sort of visual element in my own classes. Being a former art major with a drawing background before converting to philosophy, I had used drawings as what I then thought of as a crutch when I first started teaching. I later abandoned the practice when I felt more secure in my role as a teacher. It turns out that I may have been terribly wrong to toss out such a powerful pedagogical tool. My drawings, it seems, were in no way a crutch. On the contrary, if Sunni Brown (the speaker in the video) is right, they are a pedagogical enhancement.  Not only are doodles often funny and engaging, she claims, but they enhance focus as well as other dimensions of critical thinking too.

While the pedagogical dimensions are interesting, equally if not more interesting is the claim that human beings may have an innate “sense” of visual literacy that develops in a regular and predictable way.  Those working on visual argumentation may find this part of the talk very salutary indeed.

All in all, it’s an interesting 6 minutes of video.  Enjoy.

Edit: Today this video popped up in my Twitter feed courtesy of @LilyLivingstone. It perfectly illustrates the pedagogical power of the doodle in mathematics. Good stuff!

Don Lazere’s short but punchy piece in the Chronicle on the beleaguered state of critical thinking education in the American academy is well worth a read.

While I find myself agreeing with much of what he says, I think he misses one of the principal actors in the play: the increasing role of corporate influence in and on the structure and culture of American higher education.  Increasingly, administrators and board members are not professional academics but professional bureaucrats and managers who see their primary task as generating revenue.  This leads to a mentality that sees terms like ‘critical thinking’ as buzzwords, bogus assessment exercises, fodder for mission statements or worse, “branding” campaigns.  The perils therein are familiar enough and rants plentiful enough that I’ll leave it there.

What interests me the most about Lazere’s short piece is how it fits with what has really been an explosion of formal methods in the last thirty or so years.  Indeed, formal logic has changed so much that it is now virtually unrecognizable to those of us who remember the time when advances in modal logic were considered “cutting edge” to most in philosophy. From today’s perspective, the basic course in predicate calculus looks a lot like “baby logic”. ‘Critical thinking’, as Lazere points out, doesn’t seem to have much real purchase at all anymore:
